Security Threats: 5 Common Network Blind Spots

Rise of Virtualized Infrastructure

Enterprises struggle to monitor virtualized infrastructure in comparison to physical infrastructure and its proliferation and ability to scale rapidly intensifies this problem. Combine that with the ongoing drive to adopt SDN frameworks and the disruption that has caused in the data center and it's easy to see where blind spots are created.

Enterprise networks are changing at a rapid pace – becoming more complex as next-generation advancements transform traditional architectures. Simultaneously, enterprises of all kinds and across all industries are coming to the sobering conclusion that with these changes, the traditional approach to cybersecurity is no longer effective.

Perimeter defenses, while still necessary, are no longer sufficient in the face of this once inconceivable, but now irrefutable, reality: Breaches will occur. Where cyber attacks of the past were intentionally grandiose and overt, today's attackers more often prefer to move low and slow, creating command and control channels through which to steal valuable information over long periods of time while remaining undetected.

With these changes a new security paradigm is emerging, one that charges security and network professionals not only with keeping threats out, but also with gaining and maintaining visibility over what's already inside their networks; however, the increasing complexity of networks creates blind spots that make seeing these threats more difficult than ever. What's more, these blind spots are caused by a number of factors and often create bottlenecks that can degrade network performance. In this slideshow, Gigamon has highlighted the most common causes of network blind spots.

Cost reduction has been the main driver of IIoT adoption. Other contributors are the emergence of ancillary and complementary technologies, including low-power hardware devices, the cloud, Big Data analytics, robotics and automation and smart sensors. ... More >>
